I have a senior cat and I brought in 2 kittens about a year and a half ago. My senior cat has lived fairly peacefully with the younger cats but recently she (I think it's the 14 year old senior) has started peeing on the floor in front of my dresser. Because of her increased demand for water I'm thinking it may be a health issue and I'm taking her to the vet today but I would appreciate any thoughts from the rest of you. If worse comes to worse I will put a small box in front of my dresser but I hope I won't have to.
